| Abstract: | The generator low-voltage blocking inverse--time current protection can be adopted for generator or generator-transformer set or 6-10kV busbar system on generator＇s side as a backup protection against short-circuit faults under the operating conditions that the short-circuit current is smaller than the rated current of generator. Such protection can aslo be used as the remote backup proection against short circuit faults of busbars or lines on main transformer＇s side. |
